Possible Causes

Welded pump relay contacts on control board, Overheated relay due to high current draw, Moisture damage to relay board, Incorrect pump size installed

How to Fix / Troubleshooting

Safety first: Turn off power at the GFCI breaker immediately if a pump runs continuously or will not shut off.

  • Observe pump behavior: If a pump continues to run even when the topside shows it is off, the relay is likely stuck closed.
  • Inspect control pack: Remove the control pack cover (with power OFF). Look for signs of overheating or burning around the pump relay area on the Marquis/ Balboa board.
  • Check pump specifications: Verify that the installed pump matches the original Marquis specification for horsepower and amperage. Oversized pumps can over-stress relays.
  • Do not bypass relays: Never attempt to bypass a faulty relay; this is a serious safety hazard.

Resolution: Pump relay or entire control board replacement is typically required and should be performed by a qualified spa technician.
